While fishing, you make the following observations: a. Water spiders appear to be able walk on the surface of the water. b. Flat rocks may be made to skip across the water. Which of the following properties of water can explain these observations? A) Water is an excellent solvent. B) Water molecules are heavy. C) Water molecules are cohesive. D) Water molecules are polar. E) Both B and C

choice C)Water molecules are cohesive

Explanation:

The observations point to the cohesive qualities and surface tension of water.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

Water is polar and a great solvent but these are not related to the observations stated in the question.

cramming before a final is bad because it makes a student's stress level higher. students who embrace cramming to get through a final exam week find themselves struggling to perform consistently, once the brain adjusts to prolonged sleep deprivation.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
